The thickness of laminate ranges from basic 6mm planks to a more premium 8-12mm, which will resist impact better. Each will have a durability rating, too, known as Abrasion Criteria. This ranges from AC1 to AC5 for domestic use. For example, you could choose a lower rating for rooms that don’t have a lot of foot traffic, such as AC3 for a bedroom, opting for AC4 for a busy hallway or kitchen. How long or wide the boards are changes the appearance of your floor. For example, wide or long boards will create a more luxurious look. Choose a design that has an easy fit system if you’re installing it yourself – most have locking grooves that click together without the need for glue or nails. Finally, you need to think about the underlay. A compatible underlay makes your floor more comfortable to walk on, absorbs shock and noise, and insulates to help trim your energy bills.
